Wild child Rihanna has been given a day off to recover from a night out partying after missing her flight to the U.S. from London on Sunday.

Rihanna flew to London to attend a party hosted by Jay-Z and Kanye West -- and it seems she may have enjoyed herself a little too much, because she slept through her alarm.

Rihanna was photographed leaving the English capital's Dstrkt venue, where she partied with West's girlfriend Kim Kardashian, Gwyneth Paltrow and singer Rita Ora, in the early hours, but she was a no show at flight time.

Taking to Twitter.com, she revealed to fans she had missed her flight, writing, "U know life is great when u wake up at 9 am DRUNK!!!!!"

She added, "You know it was a good night when u wake up n run to your BFF's room like... 'How did I get in my bed? Did I walk? Stumble? Get carried?'"

And Rihanna later revealed pal and sometimes boss Jay-Z had given her an extra day to recover from her partying in London, writing, "I'm supposed to be on a plane rt now...! JayZ saved me!!!!! I got an extra day off sorry @HiHatprod.'"

The singer's partying antics have caused a little concern in recent weeks -- she was spotted guzzling champagne at a party in Hollywood last week and earlier this month, Rihanna was hospitalized after partying too hard at the Met Gala in New York.

Rihanna tweeted a photo of herself attached to an intravenous drip in the medical center. The latest controversy comes amid reports Rihanna has been suffering from exhaustion.
